20190190353 | DUAL SHAFT INTEGRATED MOTOR - A dual shaft integrated motor includes an inner rotor and an outer rotor that are independently rotatable and rotate in an identical pivotal direction. The inner rotor, an inner stator, an outer stator, and the outer rotor are sequentially arranged from a pivot in a radial direction. The inner stator and the outer stator interpose a non-magnetic body therebetween, the non-magnetic body being provided at a position contiguous with the inner stator and the outer stator along a circumferential direction centering on the pivot. | 2019-06-20 |
20190190354 | REINFORCED ELECTRONIC DEVICE FOR AN ELECTRICAL MOTOR - An electronic device mountable in an electrical motor, comprising: a printed circuit board with a hole for mounting a semiconductor package which comprises an integrated magnetic sensing device, the semiconductor package comprising leads; and reinforcement material; wherein the semiconductor package is mounted in the hole with the leads soldered to the printed circuit board, and wherein a gap is present between the semiconductor package and the printed circuit board, wherein the reinforcement material is at least covering part of the leads and at least part of the printed circuit board. | 2019-06-20 |
20190190355 | ELECTRICAL MACHINE AND METHODS OF ASSEMBLING THE SAME - A fluid circulating assembly having a rotation axis is provided. The fluid circulating assembly includes a fan impeller including an inlet ring and a rear plate that together define a central fan chamber. The fluid circulating assembly also includes an electrical machine having a rotor assembly, a stator assembly, and at least one bearing assembly. The rotor assembly is coupled to the rear plate such that the electrical machine is located entirely outside the central fan chamber. The rotor assembly includes a hub portion having a radially inner wall that at least partially defines a central opening extending entirely through the electrical machine and oriented about the rotation axis such that the central opening does not include a shaft extending therethrough. | 2019-06-20 |
20190190356 | STATOR, STATOR MANUFACTURING METHOD AND MOTOR - A stator includes core pieces in which at least first and second laminate members are laminated, the first laminate member includes a first tooth portion and a first core back portion, the second laminate member includes a second tooth portion and a second core back portion, the first core back portion includes a first protrusion on one side thereof in a circumferential direction and a first recess on the other side thereof in the circumferential direction, the second core back portion includes a second recess on one side thereof in a circumferential direction and a second protrusion on the other side thereof in the circumferential direction, and an area of a region in which the first and second core back portions of the core piece adjacent thereto overlap in a lamination direction is greater than a circumferential cross-sectional area of the first core back portion circumferentially inward from the first protrusion. | 2019-06-20 |
